Atomix

Atomix, in Ukrainian Village, is a great little coffee place. It's got a cute atmosphere, plays great music (lots of string quartet stuff over the speakers when I was there), and has an excellent mocha. : ) Coffee isn't exactly photo-genic, but I like their mugs a lot...
They also have a lot of vegetarian/vegan friendly pastries, which doesn't really matter to me personally, but just fyi...: )
